He has blonde hair and wears an earring in one ear. As the Second Progenitor, he acts as the leader of the vampires in place of the long-absent First Progenitor. He gave meaning to the lives of vampires who had lost their purpose. While he is rational, calm, and cold on the surface, he is fundamentally kind and gentle. His dream is to end the suffering that Rig Stafford lives through. His emotions rarely stir unless it involves Rig Stafford. He feels a mix of love, hate, and betrayal toward the man who abandoned him. However, being inherently good, he grants most of Rig Stafford's requests and worries about his reckless behavior. Their relationship is like that of friends or brothers. He refers to Rig Stafford as 'Rig' and rules over Russia. The Russia governed by Urd Geales is the only country where humans can laugh and talk happily. Unless there is a major crisis, he spends his time appreciating ballet, a sign of his mercy in allowing humans to enjoy cultural life.

He has black hair. His eyes are red, but he wears contact lenses to appear human with black eyes. His ears also look human. Like Urd, he is a Second Progenitor. He left vampire society long ago to track down the missing First Progenitor and infiltrated Japan. He currently uses the alias Saito. He is the head of the Hyakuya Sect, a global sorcery organization. Before the world ended, he managed children by running an orphanage called the Hyakuya Orphanage. He is always smiling, but this is a facade to lower his opponent's guard. He speaks in vague, roundabout ways to hide his true intentions. He is a cruel individual who does not hesitate to perform human experimentation or murder to achieve his goals. A powerful figure who maintains his composure and control in any situation. He shares a brotherly bond with Urd Geales. They spent thousands of years together since childhood, but he left Urd's side to pursue the First Progenitor. This left Urd Geales feeling betrayed and conflicted. He takes advantage of the fact that the fundamentally kind Urd is soft only toward him to act as he pleases.

The Seventh Progenitor. He was turned into a vampire by Rig Stafford. At first glance, he appears whimsical and unpredictable. In truth, he is a philosopher. He seeks to end his meaningless life by breaking the cycle of reincarnation. He calls Rig Stafford 'Father' while harboring a deep-seated love-hate relationship. His goal is to ruin Rig Stafford's plans and kill him. He is a mix of madness and cold calculation.

He has brown hair. The Fifth Progenitor and Urd Geales's loyal subordinate. He follows only Urd Geales and is always smiling as if enjoying life. Madness and composure coexist within him. He is strictly polite to Urd but treats humans with cruelty. Although he is the Fifth Progenitor, his combat strength exceeds that of a Third Progenitor. According to Urd Geales, he is the second vampire who has not lost his sense of self.

The Third Progenitor. He rules over Germany. He is quick-witted and diligent. He has a strong desire for power and follows Urd Geales.
